Abstract
Abstract Sections of wet hair on the head are rolled within, around or onto a form or roller which carries an adsorbent element, package or mass, either in a preheated or cool state. The adsorbent may be in the form of molecular sieves or may be a desiccant such as silica gel. In any case, a regenerative adsorbent is employed. Adsorption of moisture from the hair takes place rapidly through intimate contact of the hair with the foraminous wall of the adsorbent container. The hair may be dried in much less time than is required with conventional methods and damage to the hair due to blown hot air is avoided. The invention offers a natural and gentle drying process which is very rapid accompanied by some degree of hair waving.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form consisting of a flexible fabric envelope having plural compartments for said crystalline adsorbent, and a flexible fabric sleeve element carried by one end of the envelope adapted to receive a substantially rigid hair roller element, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to the forms while excluding ambient moisture.
Claim 2
Dependent Claim
121 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form consisting of a flexible fabric envelope having plural compartments for said crystalline adsorbent, and a flexible fabric sleeve element carried by one end of the envelope adapted to receive a substantially rigid hair roller element, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to the forms while excluding ambient moisture.
Claim 3
Dependent Claim
122 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form comprising a substantially rigid sleeve body having a bore and a foraminous fabric compartmented envelope mounted on and surrounding said sleeve body and containing said crystalline adsorbent in the compartments thereof, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to all of the forms while excluding ambient moisture from said chamber.
Claim 4
Dependent Claim
122 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form comprising a substantially rigid sleeve body having a bore and a foraminous fabric compartmented envelope mounted on and surrounding said sleeve body and containing said crystalline adsorbent in the compartments thereof, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to all of the forms while excluding ambient moisture from said chamber.
Claim 5
Dependent Claim
29 words
Hair drying apparatus according to claim 2, and said fabric compartmented envelope comprising a sleevE element having plural separated sleeve-like compartments and being telescoped over said rigid sleeve body.
Claim 6
Dependent Claim
137 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form comprising a substantially annular sleeve-like fabric envelope containing said mass of crystalline adsorbent, a substantially rigid sleeve-like roller cage containing the fabric envelope and said adsorbent and supporting and maintaining the shape of the envelope, said cage having a bore adapted to receive a heating element, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to all of the forms while excluding ambient moisture from said chamber.
Claim 7
Dependent Claim
137 words
Hair drying apparatus comprising a foraminous hair coiling form having a chamber for a mass of crystalline adsorbent and onto which a section of wet hair on the head may be coiled in direct contact with a foraminous portion of the form, said form comprising a substantially annular sleeve-like fabric envelope containing said mass of crystalline adsorbent, a substantially rigid sleeve-like roller cage containing the fabric envelope and said adsorbent and supporting and maintaining the shape of the envelope, said cage having a bore adapted to receive a heating element, and a cap formed separately from said form and adapted to be worn on the head enclosing a plurality of the forms with sections of wet hair coiled thereon and producing a drying chamber common to all of the forms while excluding ambient moisture from said chamber.
Claim 8
Dependent Claim
126 words
Hair drying apparatus comprising in combination a plurality of drier units each having a chamber means substantially filled with a crystalline adsorbent, each drier unit adapted to receive a section of wet hair on the head in coiled contacting relation with the unit, each unit possessing a foraminous wall portion between said chamber and said section of wet hair in contact with the unit, and a non-porous moisture-impervious cap constructed as a separate element from the drier units adapted to be worn on the head in covering relationship to said plurality of units and sections of wet hair and forming a drying chamber common to all of said units while excluding ambient moisture from the common drying chamber during the drying of hair by said units.
Claim 9
Dependent Claim
126 words
Hair drying apparatus comprising in combination a plurality of drier units each having a chamber means substantially filled with a crystalline adsorbent, each drier unit adapted to receive a section of wet hair on the head in coiled contacting relation with the unit, each unit possessing a foraminous wall portion between said chamber and said section of wet hair in contact with the unit, and a non-porous moisture-impervious cap constructed as a separate element from the drier units adapted to be worn on the head in covering relationship to said plurality of units and sections of wet hair and forming a drying chamber common to all of said units while excluding ambient moisture from the common drying chamber during the drying of hair by said units.
Claim 10
Dependent Claim
63 words
Hair drying apparatus according to claim 5, and each drier unit comprising a generally cylindrical element having inner and outer substantially concentric walls forming therebetween an annular chamber filled with said crystalline adsorbent, each unit additionally having imperforate end walls closing the ends of said annular chamber, and at least the outer cylindrical wall being perforated over a major part of its area.
